At first glance, it’s easy to assume sizing selection is best based on size of wrist or age of person using it. This is certainly one contributing factor, however over time its become clear that is isn't the only thing to consider.

Its so important especially with the wrist spikey to select best size for purpose.
The wrist spikey is used in used 2 main ways –

1. for high sensory input rolled up and down arm (the small and medium deliver this best). The smaller the more sensory input it provides when rolled. if using it to roll then, irrespective of wrist size, the small is often the go to.

2. for harm minimisation /high input when distressed (twisted and pressed into wrist buy other hand in the moment of need) – for this you want the product to be wearable and literally on hand as needed. To wear it all day you want it to not band or create restriction. When using it in this way the size isn’t what delivers the high input it’s the pressure on twisting that does. SO a comfortable wearing sizes is what you're best to select. For very small wrists the large is good but for your average child to adult it’s the XL that is best. The XXL for large/chunky wrists or ankles

The unstretched internal diameter (across) measurements are:

SMALL: 12.5 cm length - super intense for adults or for tiny child wrists.

MEDIUM: 14.5cm length - this is a great size for intense input for adult wrists to use as needed, then take off.

LARGE: 17 cm length - For all day wear for younger children or for petite wrists.

XL: 20.5cm length for the XL - usually this is the best size for ALL DAY wear for most teens & adults.

XXL: 24cm length -This is suitable for ankles and very large wrist
